Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an endless transport means consisting of a number of parallel individual rows, in particular a number of parallel belts, for transporting paper stacks of equal or different size. The present invention relates to a device for delivering paper stacks in a perpendicular direction from a feed line formed by a conveyor belt.

During the transport of paper stacks, especially during the necessary turning and delivery processes, the problem arises that free paper stacks easily slip within themselves, i.e. the paper stack loses its original rectangular shape. The problem arises that in this state it is not possible to subsequently feed this paper stack to a further processing or packaging process.

This problem has been exacerbated as production and feed rates have increased in modern machinery, and thus the problem has assumed immeasurable importance.

The problem underlying the invention is therefore to create a device for the perpendicular delivery of paper stacks from a feed line, in which deformation of the paper stacks to be delivered is reliably avoided.

The above problems are solved by the present invention as follows. This means that driven rollers capable of being lifted above the feed level of the conveyor belt are provided between the individual belts and at right angles to the feed direction, and that they are spaced above and above said rollers. The provision of an upper belt which is also oriented perpendicularly to the feed direction and is driven, and which allows a swinging movement in the feed line laterally in the feed direction for the paper stacks to be delivered. This problem can be solved by providing a stopper.

According to the invention, the rollers are mounted in a table movable upwardly and downwardly, and the upper belt is arranged in a frame likewise movable upwardly and downwardly.

According to the invention 811, separate but similar drive means are provided for upward and downward movement of the table and frame.

According to the invention, said drive means consist of two levers connected to one another via a connecting rod, pivoted to the table and to the frame, and swingable by means of a pneumatic drive.

Another feature of the invention is that the stop for the paper stack to be delivered in each case is connected in a positive rotational manner to a rocking lever actuated by a pneumatic drive.

The position of the stop can be adjusted according to the invention to different sizes of paper stacks to be delivered, and for this purpose, according to another feature of the invention, a slot is formed in the holding part of the stop.

According to the present invention, the frame is formed to be slidable on both sides Fc at right angles to the running direction of the upper belt together with the upper belt,
If the paper stacks to be delivered have different sizes, it is also possible to configure the upper belt to act on the center of the seven-layer paper stack to be constantly delivered.

With the device according to the invention, a reliable dammed delivery of the paper stack is achieved by the cooperation of the liftable rollers and the swingable stop of the lowerable upper belt, in which case deformation of the paper stack is prevented. Does not occur.

The invention will be explained in more detail below with reference to embodiments illustrated in the accompanying drawings. .

Paper stacks of different sizes are collected as shown in FIG. The body 2 is supplied to a delivery device 3. On both sides of this delivery device, for the paper stacks 2 to be delivered, they are set at right angles to the main feeder and at
A discharge device 4; 6 is provided. The undelivered paper pile runs further in the main feed direction via the belt 7.

The delivery device 6 consists of a number of driven rollers 8 arranged parallel to each other and placed in a table 9 (FIG. 2) movable upwardly and downwardly. It is supported in such a way that it protrudes through the hollow gap between the belts 7 on the lateral sides of the belt 7 and forms a lug at right angles to the direction of conveyance of the belts 7.

At both ends of this roller gang are rollers 11; 12 and 13;
Belts 16 and 17 are provided which run through the belts 4 and form a transition (FIG. 1) to the lateral transport belts 4 or 6.

For upward and downward movement of the table 9 (FIG. 2), levers 19:21 are pivotally mounted on both sides and are connected to each other via i@IEl to this table; The shafts are pivotable about shafts 23 and 24, each of which is fixed to the shaft L/-A22.

The swinging movement of the levers 19; 21 and the lifting or lowering of the table 9 relative to the rollers 8 are performed by a pneumatic drive unit 26.

Above the table 9 is a frame 2 which is likewise movable upwardly and downwardly and parallel to this table.
7 is provided, and rollers 28; 29 are provided within this frame.
Through which runs a number of driven upper belts, 31.

The upward and downward movement of the frame 27 with the upper belt 61 takes place on the same principle as the movement of the table 9. That is, this is carried out by a lever 63; 34 which is pivotally mounted on the frame 27 and is connected to each other via a connecting rod 62, and by a pneumatic drive 36.

According to FIG. 3, a stop 57, which can be pivoted out of the feed line during threading, is provided for the paper stack 2 to be delivered. This stopper 37 for this swing escape
is connected to a pneumatic drive 39 via a swing lever 38 which is rotatably connected thereto.

This stop 37 can be adjusted to different lengths of the paper stack 2, and for this purpose serves an elongated hole 42 formed in its holding part 41.

Although not shown in the drawings, the frame 27 is formed to be slidable together with the upper belt 31 at right angles to the running direction of the upper belt 31, and the frame 27 is formed so that the frame 27 can be slidable at right angles to the running direction of the upper belt 31. It is also possible to configure the paper stack 2 so that it acts on the center of the paper stack.

Since the i-deposit 2 is delivered, it swings and runs in the direction of the stopper 37 inserted therein. The roller 8 is lifted and the upper belt 3
1 is lowered onto the paper stack 2, the paper stack is gripped and sent to the discharge conveyor 4 or B according to the selected direction.

In this case, the swinging-in stop 67 and the upper belt 51 acting from above ensure the stability of the paper stack 2 during its delivery.

For this reason, in the case of through-feeding, the stopper 37 is swung out of the action field (see the dashed line in FIG. 6), the roller 8 is lowered, and the upper belt 31t'i is lifted, and in this way the paper is The stack 7 passes through the delivery device 3 on the belt 7 without being affected by the delivery device 3 in any way.
